Mens ReactX Infinity Run 4 – Lt Armory Blue/Black-Star Blue

The React Infinity series continues to evolve, with the latest iteration of Nike’s most tested shoe being the ReactX InfinityRN 4.  The big story on this fourth model cycle is the incorporation of ReactX foam – 13% more energy return with 43% less of a carbon footprint. The tweaked Flyknit upper gives you a better fit than ever, there’s even a water-repellent liner around the toebox to help with those damp days which don’t require a fully waterproof shoe.

The sole has a unique rocker design that’s shaped for support during all 3 phases of your stride, backed by a wider footprint which adds even more stability. The Nike React midsole provides a soft-yet-responsive sensation with every step. It’s flexible when you push-off, provides a smooth ride moving forwards and cushions your landing.
